ATOMlZlNG-HEAD FOR CARBONATING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 496,579, dated May 2,1893.

Application filed December 19, 1892. Serial No. 455,697. (No model.)

To all whom it nutty concern:

Be it known that 1, DAVID MUELLER, a citizen of the United States, and aresident of IIoboken, in the county of Hudson and State of New Jersey,have invented certain new and usefullmprovements in Atomizing-I-Ieadsand their Application for Oarbonatin g Liquids, of which the followingis a specification.

The object of this invention is to improve the carbonating apparatus toeffect a superior impregnation and atoinizing and mixing of the carbonicacid gas with the liquid, with a novel applied and constructed atomizinghead hereinafter specified.

In the annexed drawings forming part of this speoificationz-Figure 1,represents a vertical section through the receiver or carbonatingchamber and through my improved atomizing head applied thereto. Fig. 2,is a detached vertical section of my atomizing head on a larger scalethan in the former figure. Fig. 3, is a detached side view of the cap ofthe head. Fig. 4., is a detached side elevation of the head with the capof the same shown removed.

The letter of reference A, indicates the receiver or carbonating chamberof a liquid carbonating apparatus in which the liquid ordinarilyoccupies the lower half and the gas the upper half of its space.

13., represents my atomizin g and impregnating head, which consists ofthe main perpendicular hollow body 0, the cap D over the portion withinthe chamberA and the screw nut E and washer F over the shank of the body0 projecting down and outside of said chamber A. Said body is threadedon the bottom of the shank for connecting by a coupling the pipe fromthe liquid pump to charge the receiver. The body 0 has the flangeshoulder G to match the inner surface of the receiver from which itsshanks project down through the receiver and said shank is threaded andprovided with the screw nut E over it, and the suitably fitted washer Ffurnished between said nut and the outer surface of the receiver, sothat by this means with suitable packing the body .0 or head is tightlyscrewed to the receiver. Said body 0 projects up from the shouldertubular into the receiver vertically and to a suitable height andterminating with a semi-spherical closed top end. Close on the upperside of the shoulder G is formed a short shoulderi which is threaded andis of a larger diameter than the diameter of the tubular or cylindricalportion of the body 0 above; over which is employed the cap D with itslower end properly fitted over said threaded shoulder 2'- and providedwith a six sided rim t for turning the same by means of a suitablewrench. The top end of said cap D terminates semi-spherical and the bodyfrom the top end to the rim 2? is cylindrical with an inner diameter foran even suitable space between its inner periphery and the outerperiphery of the cylindrical and semi-spherical surface of the body 0which it covers. The bore of the body 0 is equal throughout from itsbottom end to opposite its outside spherical portion, from whichportion, said bore terminates spherically like the outside, and into theupper half portion of the cylindrical part of the body 0 are cut orsawed a suitable number of vertical radial fine slits is from its outerperiphery to its bore as shown, the only escape from the bore for theliquid and gas charged into the head. And the cap D has also a suitablenumber of fine slits w cut from its outer into its inner periphery,which slits are made into the portion of the cap near its rim t allbelow the lowest end of the slits hand out ina spirallateral directionthrough the cylindrical body of the cap. The width of the slits hand noare made narrow and much finer than round holes, could practically bedrilled, Without great difficulty and undue expense. This follows byreason that a very narrow slit can be easily and cheaply sawed throughthe atomizer walls, and since these slits are placed diagonally to eachother, they serve to break up the gas into very minute bubbles. To drillholes sufficiently fine to accomplish the same result would not only bevery diiiicult, but also very expensive, and a very slow process. Theslits 7c and m are equally distributed around the peripheries of the capD and body 0 and as close as practical without unduly reducing therequired strength of the metal between them. The

length of the slits is made sufficient for the volume of liquid to passwithout unduly increasing the pressure against the pump.

From the pump the roughly mixed carbonated liquid is charged into thebottom inlet of the body A from which it passes to and finally throughthe slits k into the space between the outer surface of the cap D andfinding no outlet above, is obliged to turn down to the slits a: andthere passes through them into the liquid contained in the receiver asshown by the arrows in Fig. 1. By passing the liquid through the slits7c and then down and through the slits m and finally through the liquidcontained in the receiver, the atomizing and mixing process ismultiplied, a greatly moved as in pouring the beverage into a glass fordrinking.

I prefer to apply the atomizing head B at the bottom of the receiver butit may be applied as shown in dotted line at the top of the receiverwith almost as good result.

What I claim as my invention, and desire to secure by Letters Patent, is

In apparatus for carbonating liquids, the combination with the receiver,A, of the atomizing head, B, consisting of the inner body, 0, having thenarrow longitudinal slits, 1c, and the outer cap, D, having the narrowdiagonal or oblique slits, 00, to the slits 70, substantially as and forthe purpose herein set forth.

Signed at New York, in the county of New York and State of New York,this 12th day of December, A. D. 1892.

DAVID MUELLER.
